Professional Applications & Engineering Value
This No. 8 x 3/8" thread forming tapping screw is engineered to address common challenges in sheet metal assembly, such as material stripping and loosening under stress. The 18-8 stainless steel composition provides excellent resistance to rust and oxidation, making it ideal for outdoor enclosures, HVAC systems, and electronic chassis. Its tamper-resistant T15 Torx drive enhances security in public or restricted-access installations, while the thread forming design creates strong, lasting threads without pre-tapping—reducing installation time and tooling costs. Compatible with a 1/8" drill bit, it ensures straightforward deployment in panels up to 0.025" thick, delivering dependable performance in industrial and commercial settings.
Specification Summary & Compliance
This screw adheres to standard inch measurements with a thread diameter of 0.164" and 18 threads per inch, meeting typical Class 2A thread tolerances for unified screw threads. The A/AB tapping screw type follows established industrial norms for thread-forming fasteners. Manufactured from RoHS and REACH-compliant 18-8 stainless steel, it ensures environmental and safety standards are met for global supply chain use.
